LAME 3.98 now handles the PCM input byteswap flag (-x) correctly, and so I've adjusted my MP3 encoding accordingly. Since there's undoubtedly lots of people using older LAME versions, I've added a run-time check to ensure either version works properly. 92fc8018bb5621409ff3cfbdc1947c79fd20fe82 Brian Langenberger bjl@usa.net 374a028e11bc25170af4f4756b09735ed55995d2 Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/9afd23779e04b91995cfd0db7e578dd7c6154567 9afd23779e04b91995cfd0db7e578dd7c6154567

Adjusted MP3's to_pcm to rename file to temp.mp3 and then decode to temp.wav before returning the PCM of temp.wav Due to an odd LAME decoding regression, it doesn't like files without suffixes any longer. cac8eff403f1305df29cc3d2cd68ddfc73137766 Brian Langenberger bjl@usa.net 8a856dc76e7d5041d2d3f69b5c527d9fdc43e82a Brian Langenberger bjl@usa.net http://github.com/tuffy/python-audio-tools/commit/374a028e11bc25170af4f4756b09735ed55995d2 374a028e11bc25170af4f4756b09735ed55995d2

2008-07-14T19:55:48-07:00

Added a preliminary workaround for the now messed-up MP3/MP2 decoding.
